【摘要】 项目实际数据的收集对于工程项目费用与进度的控制具有重要的作用。借助数学矩阵,结合 PB-S 曲线概念,建立了基础矩阵,提出了两种新的矩阵类型,以矩阵形式收集项目实际数据,通过矩阵之间的相互转化和运算,获得项目执行中费用、进度及项目进展百分比之间的关系,并绘制出实际 PB-S 曲线。结合一个五层住宅工程案例,详细展示了如何运用数学矩阵获取项目实际 PB-S 曲线。为项目管理者提供了一种简便易行的实际数据收集方法,并为基于随机 S 曲线的项目费用和进度的联合控制奠定了基础。更多还原

【Abstract】 It’s very important to collect the actual data of the project performance for schedule and cost control. Based on the mathematical matrix,combining the concept of PB-S curves,two new types of matrix are presented and some basic matrices are built.The actual data during the performing are collected in matrix forms.Through the transform and operation of matrices,the information of actual cost,schedule and project progress are obtained,and the actual PB-S curve are acquired.Using Excel software,a case study involving a 5-story housing project is performed to show the process of obtaining the PB-S curve based on the application of matrices.It provides an easy way for the project managers to collect the actual data during the project performing,and lays a foundation for the integrated control of schedule and cost based on stochastic S curves.更多还原
